' Ippumio'n ma nay-1.1901. sarilnorsaai's. memoriam" To aLZZ whom it may concern:

Be it-known that I, CARL PAUL GoERz,la

citizen of the Kingdom of Prussia, and aresidet of Friedenaujnear Berlin, Germany, address isl Rheinstrasse 45/ 46,) have invented certain new and useful Improvements in Photographic-Roll Holders,-of which'the following is a specification.

The object of the present invention is a rolllw film magazineforphotographic cameras by the peculiar construction of which the introduction Iof thefilm-spoolsiseasily done and the volume ofthe magazine is considerably reduced. Furthermore, the magazine has a I device for puncturing the .film at the end of each exposed part by means of which the operator in the dark chamber easily finds the place where to cut the film.

In the accompanying drawings, Figure 1 zo shows the magazine as seen from the back.

Fig. 2 shows the inner part, containing the spools, removed from the casing. Fig. 3 is a top view of Fig. l; Fig. 4, a section on line' A A of Fig. 2. Fig. 5 lis a section on -lineB B of- Fig. l; Fig. 6, a side elevation of Fig.2A

seen from the right. Fig. 7 is a horizontal section through line C C of Fig. 1, ltheshutter removed. Figs. 8 and 9 show top views v ofvFig. 2, the upper plate partly broken awa 3o and showing the different positions. l v alsa casingof preferred cross-section, (repopen at one of its short narrow sides. The iiat front side is `zut out to form an opeuingor window b, which ordinarily'is closed by a light-tight shutter c. A'catch-spring d holds this shutter in its closed position.

closed by a cover e,j to which is fastened a 4o wall j', which when the cover is put over the open side of the casing stands parallel to and at a very short distance from the fiat side of the casing. In the center ofthe semicircular parts of said cover e are arranged short pins` g and h, provided at their inner ends with an angular stud or spool center i., of suitable adapted to engage the-lm-spools jj.' One of these pins g has at its upper end af form,

ring by means of whichv it may' be turned.

ilo A ratchet allows the ring andthe spool to be turned only in one direction. At the edges of the wall f there are arranged Vrollers 7c perforating mechanism in T-he open narrow side isl to prevent the film yfrom rubbing oni-"the sharp edges. The pin'h is alsp provided with a ratchet-wheel l, the. purpose of which will be hereinafter explained. [In the lower part guidings two platesm, having uptnrned semicircular iiaps 'n with pins o in their centers i for engaging the core of the hlm' -spools j.

ol the wall f there are movably held by proper l Springs p draw these plates fm toward the in side.

g is a -iiu't'ed spring-pressedstgip which Y presses against thc circumference of the right other edge of the wall f to the left`spoo1j',and

may be by turning the ring shifted after each exposure somuch as. to bring a non-exposed part of it in window.

- In order to tighten the ilmfstretched 'over the wall f, lthe following arrangement is provided: Ou the cover is arranged a leverr, the pivot of which bears a pawl s, which may engagethe ratchet-wheel Zwhen turned into the positionshown inuFig.4 9, but which sets it Q free when takingthe position Fig.'8. If in front of the opening or the first position, the film may be tightened to any desired degreeby turning the pin g by means of the ring. Said pawl s'has a rearward prolongation which engages Ian arm t,

guided in the lWall' fand provided with a sharp point. By turning the lever 1" into the position Fig. 9 this arm is advanced toward l the left side and its point penetrates the iilm.- By tightening the latter a mark is torn -int'o the m, which indicates exactly to theoper-v ator the placewhere' the'lm is to` be out.

The short tube u, provided with a red' glass pane, serves for yobserving the numbers printed on the light-proof paper interposed between thespirals of the lm.

a; represents guide-rails for bringing-the stion. If they were'completeiy straight, the

lower edge of the lm passed-'eier f would be 1 4zoo easily damaged on the loweredge wof the window 1). The guide rails 'are :therefore 'innerpart'of the magazine into ifs exact pocurved slightly towardthe back," so that the Wall f is withdrawn slightly rearward from f said lower ledge tv when the edgeof the, film passes over itV andonly after having cdmpletely passed the gnidngs turn again' to their former line. Y

What I claim is- 1. In a photographic-roll holder, the coxnbination with a casing having one end closed, one of its sides being open, and guides located adjacent to said open side; of a removable roll-holder comprising a' cover for the open end of said casing, said cover carrying a depending'wall of a length to rest on the lower end of the casing when in position; lm holding and moving mechanism carried by said cover and Wall and removable therewith; and guides carried by said casin g adapted to move the lower end of said roll-holder temporarily ont of alinernent with the normal position of the holder duringits movement, at a point adjacent to the lower end of the casing.

2. In a photographic-roll holder, the conlbination witha casing having one end closed, one of its sides being open, and guides located adjacent to said open side; of a removable roll-holder comprising aI cover for the open end of said casing, said cover carrying a depending wall of a length to rest on the lower end of the casing when in position; springactuated slides located at the lower end of said wail, said cover and slides havlng opposing spool-bearings; windingmechanism carried by said cover for Winding the film from one of the spools; and guides carned by said casing adapted to move the lower end of said roll-holder temporarily ont of allnement with the normal position ot `the holder, at a point adjacent to the lower cnd of the casing.

3. In aphotographic-roll holder, the combination with a casing having one end closed, one ot' its sides being open, and guides located adjacent to said open side; of a removable roll-holder comprising a cover for the open end of said casing, said cover carrying a depending wall of a length to rest lon the lower end of the casing when in position; sliding spool-sn pportsl carried by said wall; 'a ratchet mechanism movable into and out of operative connection with one of the spools for holding the film tant; a iilin-perforating mechanism connectedv to and operable with said ratchet mechanism; and guides carried by said casing adapted to move the lower end of said roll-holder temporarily ont of alinement with the normal position of the holder, at a point adjacent to the lower end of the casing.

4. In a photographic-roll holder, an outer casing, guide-rails for the inner part attached to the longer narro'vv sides of the said casing and having their lower ends curved toward the back, and the depending Wall f, all substantially as shown and described.

In testimony whereof I aix my signature in presence of two witnesses.
